Conventionally, as a shutter device installed at the opening of a building, after receiving a fire signal from an external device (for example, a disaster prevention panel), the shutter curtain is lowered by its own weight by releasing the brake of the opening/closing machine. A shutter device has been proposed that can keep the section fully closed (see, for example, Patent Document 1). Further, in this shutter device, after receiving a fire signal, the shutter curtain is lowered by its own weight while continuing to supply power from the commercial power source to the switchgear via the control device.

Japanese Patent Application Publication No. 2008-31714

However, as mentioned above, after receiving a fire signal, the shutter curtain is lowered under its own weight while continuing to supply power from the commercial power source to the switchgear via the control device, so for example, after receiving a fire signal, there may be some influence. There is a possibility that the shutter curtain may open unintentionally if the opening/closing machine is operated incorrectly, so there is room for improvement from the perspective of increasing control reliability.

The present invention is intended to solve the problems in the prior art described above, and an object of the present invention is to provide an opening/closing control system that can improve the reliability of control.

In order to solve the above-mentioned problems and achieve the object, the opening/closing control system according to claim 1 includes an electric opening/closing control in which an opening/closing body for opening and closing an opening in a building is electrically opened/closed by a drive means.

If so, the switching means switches the supply state from the continuous state to the cutoff state.

In the opening/closing control system according to claim 2, in the opening/closing control system according to claim 1, when the abnormality occurrence signal is inputted by the input means, the switching control means causes the detection means to switch the fully closed state to the fully closed state. The supply state is maintained in the continuous state by the switching means until it is detected that the supply state is in the continuous state.

In the opening/closing control system according to claim 3, in the opening/closing control system according to claim 1 or 2, the switching control means is configured to control the supply state after the supply state is switched from the continuous state to the cutoff state by the switching means. , the supply state is changed from the cut-off state by the switching means, with at least one restoration condition being that a restoration signal indicating that the state is to be restored to the state before the abnormality occurrence signal was input is input to the input means. Switch to the continuous state.

According to the opening/closing control system according to claim 1, the switching control means is configured to be in the fully closed state by the detection means, regardless of whether dead weight closing control is performed after the abnormality occurrence signal is input to the input means. If it is detected that there is, the switching means switches the supply state from a continuous state to a cutoff state, so compared to conventional technology (technology that does not cut off power supply to the control panel or switchgear), the abnormality occurrence signal is reduced. The opening movement of the opening/closing body can be suppressed by the driving means between the time when the opening/closing body is received and the state before the reception is restored, and the reliability of the control of the opening/closing control system can be improved.

According to the opening/closing control system according to claim 2, when the switching control means receives the abnormality occurrence signal through the input means, the switching means supplies the signal until the detection means detects that the switch is in the fully closed state. Since the state is maintained in the continuous state, the supply state can be maintained in the continuous state until the fully closed state is detected after the input of the abnormality occurrence signal is received. Therefore, electric opening/closing control (for example, touch-up operation, etc.) can be reliably performed as needed, and it is possible to improve usability and safety of the opening/closing control system.

According to the opening/closing control system according to claim 3, the switching control means detects that the restoration signal has been input to the input means after the switching means switches the supply state from the continuous state to the cutoff state. As a condition, the supply state is switched from the cut-off state to the continuous state by the switching means, so that after the supply state is switched from the continuous state to the cut-off state, if the recovery condition is met, the supply state can be restored from the cut-off state to the continuous state. It becomes possible to restart the opening/closing control.

According to the opening/closing control system according to claim 4, by providing a switching means in the wiring for supplying power from the external power supply to the drive means via the control panel, the supply state can be switched between a continuous state and a cutoff state. By switching the connection state between the wiring and the external power supply using the switching means, the supply state can be switched to either a continuous state or a cutoff state, and even if the control panel is short-circuited, the driving means will not be controlled incorrectly. You can definitely avoid doing that. Furthermore, the switching means can be installed relatively easily, and the ease of installation of the switching means can be improved.

The relay side power supply section 153 supplies power supplied from the external power supply 6 to each section of the interlocking repeater 150, and also supplies the automatic closing device 70, the operating device 80, the upper limit detection section 90, the lower limit detection section 100, and the cord reel 120. , and the switching unit 130, and is configured using, for example, a known power source capable of storing electricity (for example, a battery).

(Configuration - Opening/closing control system - Interlocking repeater - Relay side control section)
The relay side control section 154 is a control means that controls each section of the interlocking repeater 150. Specifically, this control unit includes a CPU, various programs that are interpreted and executed on the CPU (including basic control programs such as the OS, and application programs that are started on the OS and realizes specific functions), and programs. A computer is equipped with an internal memory such as a RAM for storing various data.

Furthermore, as shown in FIG. 2, the relay-side control section 154 is functionally equipped with a detection section 154a and a switching control section 154b.

The detection unit 154a is a detection means that detects whether the open/close state of the opening/closing body 30 is a fully closed state.

The switching control section 154b is a switching control means that controls the switching section 130. Note that details of the processing executed by this relay-side control unit 154 will be described later.

(Configuration - Opening/closing control system - Interlocking repeater - Relay side storage)
The relay side storage unit 155 is a storage unit that stores programs and various data necessary for the operation of the interlocking repeater 150. This relay-side storage unit 155 is configured using a rewritable recording medium, and for example, a non-volatile recording medium such as a flash memory can be used.

(Opening/closing process)
Next, the opening/closing process executed by the relay side control unit 154 of the interlocking repeater 150 in the opening/closing control system 60 configured as described above will be explained. In the following description, each step is abbreviated as "S" in the description of each process shown in FIGS. 3 and 4.

The opening/closing process is a process for performing electric opening/closing control and self-weight closing control. The opening/closing process may be executed at any timing, but in the embodiment, the opening/closing process will be described as being started after the opening/closing device 1 is powered on.

Further, the premise of this opening/closing process is as follows in the embodiment. That is, the description will be made assuming that the opening/closing movement of the opening/closing body 30 is stopped by applying the brake of the opening/closing machine 40 when the opening/closing body 30 is in the fully open state. In addition, SA1, SA4 to SA9, which will be described later, will be explained as being executed regardless of whether there is a power outage or not. (This is executed using the power stored in the unit 153). Furthermore, SA2 and SA3, which will be described later, will be explained on the assumption that they are omitted in the event of a power outage.

When the opening/closing process is started, the relay side control unit 154 of the interlocking relay 150 performs processes SA1 to SA3, as shown in FIG. 3, so as to perform electric opening/closing control.

First, in SA1, the relay side control unit 154 of the interlocking repeater 150 determines whether the input of a disaster prevention signal or an emergency signal has been received. Then, when it is determined that the input of the disaster prevention signal or the emergency signal is not accepted (SA1, No), the relay side control unit 154 of the interlocking repeater 150 shifts to SA2, and the input of the disaster prevention signal or the emergency signal is not accepted. If it is determined that the request has been accepted (SA1, Yes), the process moves to SA4. In the embodiment, the input of the disaster prevention signal from the disaster prevention panel 52 is performed by an administrator or the like operating a recovery button (not shown) provided on the disaster prevention panel 52 after the detection signal is received from the fire detector 51. Applications will continue to be accepted until the end of the term.

In SA2, the relay-side control unit 154 of the interlocking repeater 150 determines whether the input of an electric close signal, an electric open signal, an electric stop signal, an upper limit detection signal, a lower limit detection signal, or an obstacle detection signal is accepted. . Then, when it is determined that the input of the electric closing signal etc. has been accepted (SA2, Yes), the relay side control unit 154 of the interlocking repeater 150 moves to SA3 and indicates that the input of the electric closing signal etc. has not been accepted. If it is determined that (SA2, No), the process moves to SA1.

At SA3, the relay-side control unit 154 of the interlocking relay 150 outputs the electric close signal, electric open signal, electric stop signal, upper limit detection signal, lower limit detection signal, or obstacle that was input by the switch 40 at SA2. Based on the detection signal, the opening/closing body 30 is electrically moved to close or open, or the opening/closing movement of the opening/closing body 30 is stopped. Thereafter, the relay side control unit 154 of the interlocking repeater 150 shifts to SA1.

Here, various control contents when an input of an electric close signal, an electric open signal, an electric stop signal, an upper limit detection signal, a lower limit detection signal, or an obstacle detection signal is received in SA2 are arbitrary, but the implementation is optional. In the form of , it is controlled as follows.

That is, when the opening/closing body 30 is electrically moved to close or open, or when the electrically driven opening/closing movement of the opening/closing body 30 is stopped, and the input of the electrically closed signal or electrically opened signal is received, the interlocking is performed. By outputting a control signal to the switch 40 via the relay side output section 152 of the repeater 150, the brake of the switch 40 is electrically released, and the drive section of the switch 40 is driven. , the opening/closing body 30 is electrically moved to close or open. In this case, for example, after the input of the electric close signal or the electric open signal is received in SA2, the operator in the building can close the opening/closing body 30 without operating the electric close button 82 or the electric open button 81 of the operating device 80. so that it can be electrically closed or opened, even if the reception of input to the electrically-driven close button 82 or the electrically-driven open button 81 stops, the signal is directed to the switch 40 via the relay-side output section 152 of the interlocking relay 150. By outputting a control signal to drive the drive unit of the opening/closing machine 40, the electrically driven closing movement or opening movement of the opening/closing body 30 may be continued.

Further, when the opening/closing body 30 is electrically moving to close or open and an input of an electric stop signal is received, a control signal is output to the opening/closing machine 40 via the relay side output section 152. As a result, the driving of the drive unit of the opening/closing machine 40 is stopped, and the brake of the opening/closing machine 40 is applied to stop the electrically driven opening/closing movement of the opening/closing body 30.

In addition, if the input of the upper limit detection signal is accepted when the opening/closing body 30 is electrically moving to open/close, a control signal is output to the opening/closing machine 40 via the relay side output section 152 to control the opening/closing operation. By stopping the driving of the drive unit of the machine 40 and applying the brake of the opening/closing machine 40, the electric opening movement of the opening/closing body 30 is stopped.

In addition, when the opening/closing body 30 is electrically moved to close, after the input of the lower limit detection signal is accepted, the lower end of the opening/closing body 30 comes into contact with the floor 4 of the room, and an obstacle detection signal is generated. If the input is accepted, a control signal is output to the switch 40 via the relay side output section 152 to stop the driving section of the switch 40 and apply the brake of the switch 40. By doing so, the electrically driven closing movement of the opening/closing body 30 is stopped (performing a so-called "touch stop operation").

In addition, when the opening/closing body 30 is electrically moved to close and the obstacle detection signal input is received before the lower limit detection signal input is accepted, the opening/closing body 30 is opened/closed via the relay side output section 152. By outputting a control signal to the switch 40, the drive of the drive unit of the switch 40 is stopped, and by applying the brake of the switch 40, the electric closing movement of the switch 30 is temporarily stopped. Next, the brake of the opening/closing machine 40 is electrically released and the driving part of the opening/closing machine 40 is driven for a predetermined period of time so that the lower end of the opening/closing body 30 is located above the current position. Then, the drive of the drive unit of the opening/closing machine 40 is stopped again, and the brake of the opening/closing machine 40 is applied to stop the electrically driven closing movement of the opening/closing body 30 (performing a so-called "touch-up operation"). However, the present invention is not limited to this, and for example, a touch stop operation may be performed. Note that after such a touch-up operation (or touch-stop operation) is performed, the opening/closing body 30 is kept in a stopped state until an input such as a disaster prevention signal of SA1 or an input of an electric release signal or the like of SA2 is received. By maintaining this, it becomes easier to avoid harm caused by obstacles.

Through these processes from SA1 to SA3, the opening/closing body 30 can be electrically moved to close or open until the input of the disaster prevention signal or emergency signal is accepted at SA1, so the opening/closing device 1 can be opened and closed normally. It becomes possible to function as a device.

Next, when the input of a disaster prevention signal or an emergency signal is accepted at SA1, the relay-side control unit 154 of the interlocking repeater 150 performs processing from SA4 to SA9, as shown in FIG. I do.

First, in SA4, the detection unit 154a of the interlocking repeater 150 detects whether the open/close state of the opening/closing body 30 is a fully closed state.

The method of detecting whether or not the fully closed state is in the fully closed state is arbitrary, but in the embodiment, the detection is based on whether or not the input of at least a lower limit detection signal is accepted. Detection is performed based on whether or not the input of the obstacle detection signal is accepted while the input of the detection signal is being accepted, and if the input of the obstacle detection signal is accepted, the fully closed state is detected. However, if the input of the obstacle detection signal is not accepted, it is detected that the door is not in the fully closed state. However, the present invention is not limited to this, and for example, the detection is simply based on whether or not the input of the lower limit detection signal is accepted, and if the input of the lower limit detection signal is accepted, the fully closed state is detected, If the input of the lower limit detection signal is not accepted, it may be detected that the state is not fully closed.

Then, when the detection unit 154a of the interlocking repeater 150 detects that it is not in the fully closed state (SA4, No), the detection unit 154a of the interlocking repeater 150 starts the dead weight closing process (SA5), and the switching control unit 154b of the interlocking repeater 150 Until the fully closed state is detected in SA4, the switching unit 130 maintains the supply state in the continuous state. Thereby, the supply state can be maintained in a continuous state until the fully closed state is detected after the input of the disaster prevention signal or the emergency signal is received. Therefore, electric opening/closing control (for example, touch-up operation, etc.) can be performed as necessary, and usability and safety of the opening/closing control system 60 can be improved. On the other hand, if the fully closed state is detected (SA4, Yes), the process moves to SA6.

(Opening/closing process - Dead weight closing process)
Next, the dead weight closing process (SA5) shown in FIG. 3 will be explained. The dead weight closing process is a process for closing and moving the opening/closing body 30 by its own weight.

As shown in FIG. 4, first, at SB1, the relay-side control unit 154 of the interlocking repeater 150 determines whether the input of the obstacle detection signal has been accepted. Then, when it is determined that the input of the obstacle detection signal is not accepted (SB1, No), the relay side control unit 154 of the interlocking repeater 150 shifts to SB2, and the input of the obstacle detection signal is not accepted. If it is determined that (SB1, Yes), the process moves to SB3.

At SB2, the relay-side control unit 154 of the interlocking relay 150 causes the automatic closing device 70 to close and move the opening/closing body 30 by its own weight. Specifically, by outputting a control signal to the automatic closing device 70 via the relay side output section 152 of the interlocking relay 150 and mechanically releasing the brake of the opening/closing machine 40, the opening/closing body 30 is closed by its own weight. Move closed. Thereafter, the relay-side control unit 154 of the interlocking repeater 150 ends the dead weight closing process and moves to SA4 in FIG. 3.

At SB3, the relay-side control unit 154 of the interlocking relay 150 causes the automatic closing device 70 to stop the closing movement of the opening/closing body 30 due to its own weight.

Here, the method of stopping the closing movement of the opening/closing body 30 due to its own weight is arbitrary, but in the embodiment, it is stopped as follows. That is, when the opening/closing body 30 is moving to close due to its own weight in a non-power outage state, the automatic closing device 70 returns the release operation part of the switch 40 to the state before the release operation, so that the opening/closing body 30 is closed by its own weight. By switching from a state where the brake is mechanically released to a state where the brake of the opening/closing machine 40 is applied, the closing movement of the opening/closing body 30 due to its own weight is temporarily stopped. Next, the brake of the opening/closing machine 40 is electrically released and the driving part of the opening/closing machine 40 is driven for a predetermined period of time so that the lower end of the opening/closing body 30 is located above the current position. Next, the driving of the drive unit of the opening/closing machine 40 is stopped again, and the brake of the opening/closing machine 40 is applied to stop the electrically driven closing movement of the opening/closing body 30 (a so-called "touch-up operation" is performed. However, The invention is not limited to this, and for example, as described above, the "touch stop operation" in SA3 of FIG. will be carried out.

At SB4, the relay-side control unit 154 of the interlocking repeater 150 determines whether a predetermined period of time (for example, 10 seconds, etc.) has elapsed since the input of the obstacle detection signal accepted at SB1 was no longer accepted. Then, the relay-side control unit 154 of the interlocking repeater 150 waits until it is determined that the predetermined time has elapsed (SB4, No), and when it is determined that the predetermined time has elapsed (SB4, Yes). Then, the process moves to SB2, and the self-weight closing movement of the opening/closing body 30 by the automatic closing device 70 is restarted in accordance with the specific control contents of SB2 described above.

Through such dead weight closing processing, when the input of the obstacle detection signal is accepted at SB1, the closing movement of the opening/closing body 30 due to its own weight can be stopped until a predetermined period of time has elapsed, and the safety of the obstacle can be maintained. Can be secured. Further, after the predetermined time has elapsed, the self-weight closing movement of the opening/closing body 30 by the automatic closing device 70 can be restarted, and even after an obstacle is detected, the fully closed state can be reliably achieved.

Returning to FIG. 3, after the fully closed state is detected in SA4 (SA4, Yes), in SA6, the relay side control unit 154 of the interlocking relay 150 causes the automatic closing device 70 to move the opening/closing body 30 to close due to its own weight. to stop.

Although the method of stopping the closing movement of the opening/closing body 30 due to its own weight is arbitrary, in the embodiment, it is stopped as follows.

That is, when the opening/closing body 30 is moving to close due to its own weight, a control signal is output to the automatic closing device 70 via the relay side output section 152, and the automatic closing device 70 operates the release operation section of the opening/closing machine 40. By returning to the state before the release operation, the brake of the opening/closing machine 40 is switched from a mechanically released state to a state where the brake of the opening/closing machine 40 is applied, thereby preventing the closing movement of the opening/closing body 30 due to its own weight. (Perform a so-called "touch stop operation").

Further, when the opening/closing movement of the opening/closing body 30 by electric power or its own weight is stopped, the stopped state is maintained.

In SA7, the switching control unit 154b of the interlocking repeater 150 causes the switching unit 130 to switch the supply state from the continuous state to the cutoff state (that is, after the disaster prevention signal or emergency signal is input, the switching control unit 154b of the interlocking repeater 150 determines whether dead weight closing control has been performed or not. If it is detected that it is in the fully closed state regardless of whether the Specifically, the switching unit 130 switches the connection state between the external power supply side wiring 5a and the external power supply 6 to a state where they are not electrically connected, thereby switching to the cutoff state. As a result, compared to conventional technology (technology that does not cut off the power supply to the control panel 140 or the switchgear), the switchgear 40, it is possible to suppress the opening/closing body 30 from opening and moving, thereby increasing the reliability of control of the opening/closing control system 60.

At SA8, the switching control unit 154b of the interlocking repeater 150 determines whether the restoration conditions are satisfied. Here, "recovery condition" means a condition for switching the supply state from a cutoff state to a continuous state.

Further, the method for determining whether or not this restoration condition is satisfied is arbitrary, but for example, the determination may be made based on whether at least a restoration signal is input to the relay-side input section 151. As an example, if the switching unit 130 is a breaker, it is determined whether the input of the recovery signal is accepted and a predetermined operation is received on the switching unit 130 (specifically, whether a predetermined operation is received from the switching unit 130). If a recovery signal is input and a prescribed operation is accepted, it is determined that the recovery conditions are met, and the recovery signal is input. If the predetermined operation is not accepted, it may be determined that the recovery condition is not satisfied. In addition, when the switching unit 130 is a relay contact, the determination is made based on whether or not the input of the restoration signal has been accepted, and if the restoration signal has been input, it is determined that the restoration conditions are met, and the restoration is restored. If no signal is input, it may be determined that the recovery condition is not satisfied.

Then, the switching control unit 154b of the interlocking repeater 150 waits until it is determined that the restoration condition is satisfied (SA8, No), and when it is determined that the restoration condition is satisfied (SA8, Yes), it moves to SA9.

At SA9, the switching control unit 154b of the interlocking repeater 150 causes the switching unit 130 to switch the supply state from the cutoff state to the continuous state. Specifically, when the supply state is a cutoff state, the switching unit 130 switches the connection state between the external power supply side wiring 5a and the external power supply 6 to a state where they are electrically connected, so that the supply state is switched to the continuous state. to switch to. After processing SA9, the relay-side control unit 154 of the interlocking repeater 150 moves to SA1, and repeats the processing from SA1 to SA9.

Through the processing of SA8 and SA9, after the supply state is switched from the continuous state to the cutoff state, if the recovery conditions are met, the cutoff state can be restored to the continuous state, and the electric opening/closing control can be restarted. .

In addition, by the opening/closing process as described above, the switchgear 1 can function as a normal switchgear until the input of the disaster prevention signal or the emergency signal is accepted, and the input of the disaster prevention signal or the emergency signal is accepted. In addition, after entering the fully closed state, the opening/closing device 1 can also function as a firewall.

(effect)
According to the embodiment, the switching control unit 154b causes the detection unit 154a to fully close the switch regardless of whether dead weight closing control is performed after the abnormality occurrence signal is input to the relay side input unit 151. If it is detected that the power supply is in the state, the switching unit 130 switches the supply state from the continuous state to the cutoff state. To improve the reliability of control of the opening/closing control system 60 by suppressing the opening/closing body 30 from opening/closing by the opening/closing machine 40 between receiving the abnormality occurrence signal and restoring the state before receiving the signal. I can do it.

Further, when the switching control section 154b receives an abnormality occurrence signal from the relay side input section 151, the switching section 130 changes the supply state to the continuous state until the detection section 154a detects that the switching control section 154b is in the fully closed state. Therefore, the supply state can be maintained in a continuous state until the fully closed state is detected after the input of the abnormality occurrence signal is received. Therefore, electric opening/closing control (for example, touch-up operation, etc.) can be reliably performed as needed, and it is possible to improve usability and safety of the opening/closing control system 60.

Further, the switching control unit 154b sets, as at least one recovery condition, that a recovery signal is input to the relay side input unit 151 after the switching unit 130 switches the supply state from the continuous state to the cutoff state. Since the supply state is switched from the cut-off state to the continuous state, if the recovery condition is met after the supply state is switched from the continuous state to the cut-off state, the cut-off state can be restored to the continuous state, and the electric opening/closing control is restarted. becomes possible.

In addition, by providing a switching unit 130 in the external power supply side wiring 5a for supplying power from the external power supply 6 to the switchgear 40 via the control panel 140, the supply state can be switched to either a continuous state or a cutoff state. This makes it possible to switch the supply state to either a continuous state or a cutoff state by switching the connection state between the external power supply side wiring 5a and the external power supply 6 by the switching unit 130, and even if the control panel 140 is short-circuited, the switch Therefore, it is possible to reliably avoid erroneously controlling the 40. Further, the switching unit 130 can be installed relatively easily, and the installation efficiency of the switching unit 130 can be improved.

Further, since the switching section 130 is a breaker or a relay contact, the switching section 130 can be manufactured easily and at low cost, and the manufacturability of the switching section 130 can be improved.

[III] Modifications to the Embodiments The embodiments of the present invention have been described above, but the specific configuration and means of the present invention are within the scope of the technical idea of each invention described in the claims. , can be modified and improved as desired. Hereinafter, such a modified example will be explained.

(About the problems to be solved and the effects of the invention)

In addition, it may solve only a part of the described problem or produce only a part of the described effect. For example, even if the convenience for the operator of the switchgear according to the present invention is the same as that of the conventional one, if the convenience for the operator is the same as that of the conventional one due to a structure different from the conventional one, the problem of the present application is solved. are doing.

(About distribution and integration)
Further, each of the electrical components described above is functionally conceptual, and does not necessarily need to be physically configured as shown in the drawings. In other words, the specific form of distribution and integration of each part is not limited to what is shown in the diagram, and all or part of it may be functionally or physically distributed or integrated in arbitrary units depending on various loads and usage conditions. can be configured. Furthermore, the term "device" in this application is not limited to one configured by a single device, but includes one configured by a plurality of devices. Further, the data structure of each piece of information described in the above embodiments may be changed arbitrarily. For example, the interlocking repeater 150 is configured to be distributed among a plurality of devices that are configured to be able to communicate with each other, and the relay side control section 154 is provided in some of these devices, and the A relay side storage unit 155 may be provided in part.

(About shape, numbers, structure, time series)
With respect to the components illustrated in the embodiments and drawings, the shape, numerical values, structure or chronological relationship of multiple components may be arbitrarily modified and improved within the scope of the technical idea of the present invention. I can do it.

(About fire alarm system)
In the above embodiment, it has been explained that the opening/closing device 1 includes the fire alarm system 50, but the present invention is not limited to this, and for example, the fire alarm system 50 may be omitted. In this case, in SA1 of the opening/closing process, it may be determined whether or not only the input of the emergency signal has been accepted.

(About opening/closing control system)
In the above embodiment, it has been described that the opening/closing control system 60 includes the interlocking repeater 150, but the present invention is not limited to this, and for example, the interlocking repeater 150 may be omitted.

In this case, for example, the automatic closing device 70 may be provided with the relay side input section 151, the detection section 154a, and the switching control section 154b. Further, the automatic closing device 70, the disaster prevention panel 52, the operating device 80, and the switching unit 130 are directly connected via the wiring 5, and the control panel 140 and the operating device 80 are directly connected via the wiring 5. may be done. Thereby, the control panel 140 can perform electric opening/closing control based on the electric opening signal etc. input from the operating device 80 via the wiring 5. Further, when the relay side input unit 151 receives input of a disaster prevention signal and an emergency signal from the disaster prevention panel 52 or the operating device 80 via the wiring 5, the automatic closing device 70 mechanically releases the brake of the opening/closing machine 40. The opening/closing body 30 can be moved closed by its own weight. Further, when the detection unit 154a detects that the fully closed state is detected, the automatic closing device 70 returns the release operation unit of the opening/closing machine 40 to the state before the release operation, thereby causing the closing body 30 to move under its own weight. After that, the switching control section 154b can cause the switching section 130 to switch the supply state from the continuous state to the cutoff state.

(Regarding the relay side input section, detection section, and switching control section)
In the above embodiment, it has been explained that the relay side input section 151, the detection section 154a, and the switching control section 154b are provided in the interlocking repeater 150, but the invention is not limited thereto. It may be provided in the device 70. In this case, the relay-side input unit 151 may receive input of the disaster prevention signal, emergency signal, or lower limit detection signal through the wiring 5 but not through other devices such as the interlocking relay 150. Alternatively, input of a disaster prevention signal, an emergency signal, or a lower limit detection signal may be received via the other device described above. Further, the switching control section 154b may be directly connected to the switching section 130 through the wiring 5 but not through any other device, or may be connected indirectly through the wiring 5 and the other device described above. good.

As an example, if the disaster prevention panel 52 is provided with the switching control section 154b and the disaster prevention panel 52 and the switching section 130 are directly connected via the wiring 5, in SA7 of the opening/closing process, the switching control section 154b When a signal indicating the fully closed state is received from the interlocking repeater 150 after processing SA6, the switching unit 130 may switch the supply state from the continuous state to the cutoff state.

(About the switching part)
In the above embodiment, it has been explained that the switching unit 130 is a breaker or a relay contact, but it is not limited to this, and may be a special switching circuit that can switch the supply state between a cutoff state and a continuous state, for example. good.

(About the upper limit detection section and lower limit detection section)
In the above embodiment, the upper limit detection section 90 and the lower limit detection section 100 are described as counter-type limit switches, but the present invention is not limited to this. For example, it may be possible to detect whether the position of the lower end of the opening/closing body 30 has reached the upper limit position or the lower limit position (specifically, a roller lever type limit switch, a photoelectric sensor, a sonic sensor, etc.). good.

(About electric open signal, electric close signal, electric stop signal, emergency signal, recovery signal)
In the above embodiment, it has been explained that the relay side input unit 151 receives inputs of the electric open signal, the electric close signal, the electric stop signal, the emergency signal, and the recovery signal from the operating device 80, but the invention is not limited thereto. For example, an external device such as a center device installed in another room or another building can be used to control the opening and closing of the opening/closing body 30 by remote control even from a position away from the room where the opening/closing device 1 is installed. It may be accepted from

(About opening/closing process)
In the above embodiment, in the process of SA3, after the input of the electric close signal or the electric open signal is accepted in SA2, when the reception of the input of the electric close signal or the electric open signal by the relay side input unit 151 is stopped. Although it has been described that the opening/closing body 30 is electrically moved to close or open, the present invention is not limited to this. For example, the relay side input may be configured such that the opening/closing body 30 can be electrically closed or opened only while the electrically operated close button 82 or electrically operated open button 81 of the operating device 80 is operated by the operator in the building. The opening/closing body 30 may be electrically moved to close or open only while the input from the electrically-driven close button 82 or the electrically-driven open button 81 is being accepted by the section 151.

(Additional note)
The opening/closing control system of Supplementary Note 1 performs electric opening/closing control in which an opening/closing body for opening and closing an opening in a building is electrically opened and closed using a driving means, and also performs dead weight closing control in which the opening/closing body is closed and moved by its own weight.

Regardless of whether or not the self-weight closing control is performed after the input to the means, if the detection means detects that the fully closed state is in the fully closed state, the switching means causes the supply state to be switched to the continuation state. state to the cutoff state.

In the opening/closing control system according to appendix 2, in the opening/closing control system according to appendix 1, the switching control means detects that the fully closed state is determined by the detection means when the abnormality occurrence signal is inputted by the input means. Until the detection is detected, the switching means maintains the supply state in the continuous state.

In the opening/closing control system according to appendix 3, in the opening/closing control system according to appendix 1 or 2, the switching control means is configured to detect the occurrence of the abnormality after the supply state is switched from the continuous state to the cutoff state by the switching means. The switching means changes the supply state from the cut-off state to the continuous state, with at least one restoration condition being that a restoration signal indicating that the state is to be restored to the state before the signal was input is input to the input means. Let them switch.

The opening/closing control system according to appendix 4 is the opening/closing control system according to any one of appendices 1 to 3, which includes a control panel for controlling the drive means, and supplies power from the external power source to the control panel through the control panel. By providing the switching means in the wiring for supplying to the driving means, the supply state can be switched to either the continuous state or the interrupted state.

The opening/closing control system according to appendix 5 is the opening/closing control system according to any one of appendices 1 to 4, in which the switching means is a breaker or a relay contact.

(Effect of appendix)
According to the opening/closing control system described in Supplementary Note 1, the switching control means is in the fully closed state by the detection means, regardless of whether dead weight closing control is performed after the abnormality occurrence signal is input to the input means. If this is detected, the switching means switches the supply state from the continuous state to the cutoff state, so compared to conventional technology (technology that does not cut off the power supply to the control panel or switchgear), the abnormality signal is reduced. The opening movement of the opening/closing body can be suppressed by the driving means between reception and restoration to the state before the reception, and the reliability of the control of the opening/closing control system can be improved.

According to the opening/closing control system described in Supplementary note 2, when the switching control means receives an abnormality occurrence signal through the input means, the switching means changes the supply state until the detection means detects that the fully closed state is reached. Since the supply state is maintained in the continuous state, the supply state can be maintained in the continuous state until the fully closed state is detected after the input of the abnormality occurrence signal is received. Therefore, electric opening/closing control (for example, touch-up operation, etc.) can be reliably performed as needed, and it is possible to improve usability and safety of the opening/closing control system.

According to the opening/closing control system described in Supplementary Note 3, the switching control means sets at least one restoration condition that the restoration signal is input to the input means after the switching means switches the supply state from the continuous state to the cutoff state. As a result, the supply state is switched from the cutoff state to the continuous state by the switching means, so that after the supply state is switched from the continuous state to the cutoff state, if the recovery condition is met, the supply state can be restored from the cutoff state to the continuous state. Control can be resumed.

According to the opening/closing control system described in Appendix 4, by providing a switching means in the wiring for supplying power from an external power source to the drive means via the control panel, the supply state can be set to either a continuous state or a cutoff state. By switching the connection state between the wiring and the external power source using the switching means, the supply state can be switched to either a continuous state or a cutoff state, and even if the control panel is short-circuited, the driving means will not be controlled incorrectly. You can definitely avoid that. Furthermore, the switching means can be installed relatively easily, and the ease of installation of the switching means can be improved.

According to the opening/closing control system described in Appendix 5, since the switching means is a breaker or a relay contact, the switching means can be manufactured easily and inexpensively, and the manufacturability of the switching means can be improved.
